Question

The equation y=100x represents the distance y in kilometers that a car can travel in x hours. Determine whether there is a constant of variation. If so, explain what it represents in this situation

Answer 1

100

Explanation:

Give the equation :

y = 100x

The equation above is expressed using the general formof a direct variation ; where ;

a varies directly as x equals

a = kx

Where, k = constant of proportionality

Comparing this with the equation above, we can conclude that, the above equation has a constant of variation, k which is equal to 100
